I have always considered The Silence of the Lambs (1991) one of my favorite films since I've never seen characters like Dr. Hannibal Lecter, who seems as evil as astute and intelligent. The cannibal never seems to show his real intentions to Clarice but digging bit by bit into Clarice's past in exchange for his help. This interaction makes the relationship between Clarise and Dr. Hannibal interesting in that both want something from the other but significantly impact the film's rhythm.
I felt Clarise wanted so badly to succeed in his goal of finding the so-called Jame Gump, to the point of sharing something about her past with Dr. Lecter. In addition, I could see in Clarise's eyes a mix between nostalgia and sadness at the same time. Even though we don't know the scene where she tries to free the lamps, I could imagine that just looking at her and what it meant for her to wish to make the lights scream disappear will relieve her from her pain and agony.
Find redemption. That's why I thought Doctor Hannibal helped at the last minute. Dr. Lecter's desires go beyond what most people could guess.
From my perspective, what made Buffalo Bill the monster is the psychological disorder he seems to have, how he would like to be, and had born in another body and had another life. But, moreover, he has a life where those women who love him that he kidnapped.
